Use the given function f(x) = (x-4) +8x to solve f(-2)A. 18
B. 14
C. 22
D. -22

Answers

Answer 1
Answer: we just need to substitute the x by -2 in the function:
f(x) = (x - 4) + 8x
f(-2) = (-2 - 4) + 8(-2)
f(-2) = (-6) - 16
f(-2) = -6 - 16
f(-2) = -22

your answer is 3/5b + 79.50 = 132.50.
3/5b +79.50 = what - like an algebra question solve for b.
3/5b +79.50 = -79.50
         - 79.50
3/5b = 79.50
5/3 x 3/5 b = 79.50 x 5/3
b - 79.50/1 x 5/3 = 397.50/3 
b = 132.50

C.2÷0.25=s
D.s÷0.25=2

We use .25 L of milk per serving, so we can have at most 2/(0.25)=8 servings hence it's 2/.25=s, which can be rewritten as s*0.25=2

Find the slope of the line that goes through the given points.
(7,2) and (5,2)

Answers

Answer: 0

Step-by-step explanation:

describes a horizontal line

so slope = 0

Answer:

0/2

Step-by-step explanation:

you have to subtract the x's and then then the y's, y is always on top. So, y=2-2/ x= 7-5 making 0/2 When the 0 is on the "top" of the fraction, that would mean that the two y-values are the same.
